HI Kenny This isn't really a BlueZ question. You would need to either compile the package from source yourself or either just upgrade to a newer version of your distro. The distro version you are using has less than 2 years left of support, why not go with 20.04 LTS instead which has a longer support duration?

We are using BlueZ 5.48 in embedded Ubuntu 18.04. We're trying to build BlueZ 5.50 for embedded Ubuntu 18.04 because we need the "Service Changed Indication" feature which was fixed in 5.50. The host system to build BlueZ is Ubuntu 18.04. I downloaded the BlueZ 5.50. The CPU on the embedded device is "Freescale i.MX6 UltraLite". As we need to cross compile the BlueZ, I suppose we need to use the option "--host=arm-linux-gnueabihf". Is that the correct option for cross-compilation? Here is the configure command: ./configure --host=arm-linux-gnueabihf --prefix=/usr --mandir=/usr/share/man --sysconfdir=/etc --localstatedir=/var But there were errors when we ran the command above: checking for GLIB... no configure: error: GLib >= 2.28 is required So I installed these packages: sudo apt-get install libglib2.0 sudo apt-get install glib2.0 But I still got the same errors even if the packages above were installed. It seems GLib is 2.27 for Ubuntu 18.04. If that is the case, how can I get GLib version 2.28 or above in order to get configure working? Thanks in Advance!
